What are the prerequisites for creating a Fault Set? (Choose two)
The correct answer is A. At least 3 nodes in the cluster B. Predefined Protection Domain. Creating a Fault Set requires at least 3 nodes (A) because the system needs enough nodes outside the fault set to maintain data redundancy if an entire fault set fails - fewer nodes cannot guarantee rebuild capacity. A predefined Protection Domain (B) is also mandatory because…

Explanation
Creating a Fault Set requires at least 3 nodes (A) because the system needs enough nodes outside the fault set to maintain data redundancy if an entire fault set fails - fewer nodes cannot guarantee rebuild capacity. A predefined Protection Domain (B) is also mandatory because Fault Sets are logical groupings defined within a Protection Domain, so that container must exist first.
C (Existing Storage Pool) is incorrect because Storage Pools are created after the Protection Domain and are not a dependency for defining a Fault Set. D (Enabled deduplication) is a data efficiency feature entirely unrelated to fault tolerance configuration.
Memory tip: Think "3 nodes, 1 domain" - you need a minimum cluster size to survive a fault set failure, and you need the Protection Domain as the parent container before you can place nodes into fault groups within it.
